What ITM, ATM, and OTM actually mean
ITM means in the money: the option already has intrinsic value. ATM means at the money: price and strike are roughly equal. OTM means out of the money: the option has no intrinsic value.
For calls and puts, the logic is mirrored. A call is ITM when spot is above strike. A put is ITM when the strike is above spot.
A simple example with spot at 100 EUR
- Call strike 90 ITM because you could buy below the market.
- Call strike 100 ATM because spot and strike are roughly equal.
- Call strike 110 OTM because exercise has no benefit right now.
- Put strike 110 ITM because you could sell above the market.
- Put strike 90 OTM because selling at 90 is unattractive right now.
